The great difiicnity in designing i mii for ,it wiii be seen by the :ibo-vc construction SG a heating engine is to provide means foi' that we mziic si if'eiy snhstaniini pape-r'roii firmly securing the biades te the mii so that which Wiii 'Withsmid the severe stiins to ihey will not become disiodged When undef which paper iciis are subjeced and in which the severe strains to whiciii ihey are suhi'zebiadeswiiibe heid i fdiy7 and the bladejected, and aise i0 provide means which can can be readiiy remcved should it ne desired 85 be readily detached when ic is desired tc io i'epiaeesny one ci' a sei-ics ci? them. i'enicve cnc ci: incre ci the bisdes from the ive ciaiin:
